This variable is a specific audio device to open when the "default" audio device is used.

This hint will be ignored when opening the default playback device if SDL_HINT_AUDIO_ALSA_DEFAULT_PLAYBACK_DEVICE is set, or when opening the default recording device if SDL_HINT_AUDIO_ALSA_DEFAULT_RECORDING_DEVICE is set.

This hint should be set before an audio device is opened.

This hint is available since SDL 3.2.0.
